Raahim gave ¼ of a pizza to his sister, another ¼ to his mother and 1/3 of the remaining to his father. What fraction of the pizza is left for his brother Saim?
Answers
Answer:
tom ate 1/4 pizza, so that left him with 3/4 pizza.
Now that 3/4 is divided into 1/12 , so now he got 3/4 : 1/12
= 9 slices of 1/12 pizzas , or 9/12 of the original pizzas
Now it remained 1/6 or 2/12 of the original pizzas.
which mean, the amount of friends that got pizza are : 9 - 2 = 7 friends

g Consider a multiple-choice question exam consisting of 20 questions. Assume that each question has five possible choices, and only one of them is correct. If a student is going to guess solutions at the exam, what is the probability that he answers at most three of them are correct
Answers
Answer:
0.4114 = 41.14% probability that he answers at most three of them are correct
Step-by-step explanation:
For each question, there are only two possible outcomes. Either it is answered correctly, or it is not. The probability of a question being answered correctly is independent of any other question. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
20 questions:
This means that [tex]n = 20[/tex]
Assume that each question has five possible choices, and only one of them is correct.
This means that [tex]p = \frac{1}{5} = 0.2[/tex]
What is the probability that he answers at most three of them are correct?
This is:
[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)[/tex]
So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{20,0}.(0.2)^{0}.(0.8)^{20} = 0.0115[/tex]
[tex]P(X = 1) = C_{20,1}.(0.2)^{1}.(0.8)^{19} = 0.0576[/tex]
[tex]P(X = 2) = C_{20,2}.(0.2)^{2}.(0.8)^{18} = 0.1369[/tex]
[tex]P(X = 3) = C_{20,3}.(0.2)^{3}.(0.8)^{17} = 0.2054[/tex]
[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.0115 + 0.0576 + 0.1369 + 0.2054 = 0.4114[/tex]
0.4114 = 41.14% probability that he answers at most three of them are correct
Consider a circle with center (2,-3) that passes through the point (5,4).
What is the equation of the described circle?
A) (x - 2)^2 + (y + 3)^2 = 58
B) (x - 2)^2 + (y + 3)^2 = 68
C) (x + 2)^2 + (y - 3)^2 = 58
D) (x + 2)^2 + (y - 3)^2 = 68
If the circle passes through the point (6,5), what is the equation of the new circle with the same center?
A) (x + 2)^2 + (y - 3)^2 = 80
B) (x + 2)^2 + (y - 3)^2 = 90
C) (x - 2)^2 + (y + 3)^2 = 80
D) (x - 2)^2 + (y + 3)^2 = 90
Answers
Answer: Part A: A. Part B: C
Step-by-step explanation:
Substitute the number into the equation of circle: (x-h)^2 + (y-k)^2=r^2
h and k are 2, -3 so you will need to change their signs.
The final thing you will do is to find the distance of center to point. Using distance formula and you will able to find the radius. Square your radius then the result will be there

AD = 6m
Step-by-step explanation:
Sin(30) = AD / 12
Sin(30) * 12 = AD
6 = AD
Hope this helps!
Find AD.
[tex] \sf a. \: 2\sqrt{3} \: m[/tex]
[tex] \sf b. \: 3 \sqrt{3} \: m[/tex]
[tex] \sf c. \: 6 \: m[/tex]
[tex] \sf d. \: 6 \sqrt{3} [/tex]
____________________
Solution :-Given Information :-∠DCB = 30°∠BDC = 90°∠ABC = 90°BC = 12 mTo Find :-The Length of AD Calculation :-Here, Sin θ is 30°
Sin = [tex] \bf \frac{perpendicular}{hypotenuse} [/tex]
Here, θ is 30°
Substituting the values, We get,
∴ Sin ( 30 ) = [tex] \sf \frac{AD}{BC} [/tex]
Substituting the value of BC as 12, We get,
⇒ Sin ( 30 ) = [tex] \sf \frac{AD}{12} [/tex]
Transposing 12 to Left Hand Side, We get,
⇒ Sin ( 30 ) × 12 = AD
Calculating further, We get,
⇒ AD = 6 m
∴ AD = 6 m
____________________Final Answer :-The Length of AD is 6 m

Carlos es 7 años mayor que José. Dentro de tres
años la suma de sus edades es 21.
¿Cuáles son sus edades ahora?
Answers
Answer:
Carlos tiene 11 años, mientras que José tiene 4 años.
Step-by-step explanation:
Dado que Carlos es 7 años mayor que José, y dentro de tres años la suma de sus edades será 21, para determinar cuáles son sus edades ahora se debe realizar el siguiente cálculo:
21 - 7 - 3 = X
14 - 3 = X
11 = X
11 - 7 = 4
Así, Carlos tiene 11 años, mientras que José tiene 4 años.

Answers
1 hour 42 minutes 1 hour 32 minutes+1 hour 38 minuts+1 hour 30 minutes
Answers
Answer:
382
Step-by-step explanation:
Just add all of them and 1 hour equals 60 mins
First, lets add the hours.
1 hour + 1 hour + 1 hour = 3 hours
Now, let's add the minutes,
42 minutes + 32 minutes + 38 minutes + 30 minutes = 142 minutes
1 hour = 60 minutes
How many grouped 60's are there in 142? There are 2 full 60s in 142 minutes.
2 60s = 120 minutes
Add 2 hours, but subtract 120 minutes.
142 minutes - 120 minutes = 22 minutes
So, the final answer is 5 hours and 22 minutes.

Use the figure to find the measures of the numbered angles.
Parallel lines a and b are intersected by a transversal t. Angle 1 and angle 99 degrees are supplementary angles. Angle 1 and angle 3 are vertical angles. Angle 2 and angle 99 degrees are vertical angles. Angle 99 degrees and angle 4 degrees are corresponding angles on the same side of the transversal. Angle 1 and angle 5 are corresponding angles on the other side of the transversal. Angle 5 and angle 7 are vertical angles. Angle 6 and angle 4 are vertical angles.

Answer:
∠1 = ∠3 = ∠5 = ∠7 = 81°
∠2 = ∠4 = ∠6 = 99°
Step-by-step explanation:
Vertical and corresponding angles are congruent. Angles 1 and 99° are supplementary, so ...
∠1 = 180° -99° = 81°
Then we have ...
∠1 = ∠3 = ∠5 = ∠7 = 81°
∠2 = ∠4 = ∠6 = 99°

Little's law can be applied to any part of the store, such as a particular department or the checkout lines. The store owner determines that, during business hours, approximately 84 shoppers per hour make a purchase and each of these shoppers spend an average of 5 minutes in the checkout line. At any time during business hours, about how many shoppers, on average, are waiting in the checkout line to make a purchase at the Good Deals Store?
Answers
Number of shoppers per hour (during business hours) = 84
Time spent by each shopper (average) = 5 mins
Now,→ 60 mins (1 hour) = 84 shoppers
→ 60 = 84
→ 84/60
→ 1.4
→ 1.4 × 5 = 7
→ 7 shoppers on an average, are waiting in the checkout line to purchase at the "Good Deals store"
